Implementation of circular polarization in 2020, cooperation with SwissFEL

     Boundary condition of the design considered was minimum invasiveness to the SwissFEL/PSI
     undulator layout with the main goal to decrease implementation costs.

     Afterburner sections length (2 m) and the precise mechanics were selected to be the same in
     both cases for the European XFEL afterburners and the undulator of SwissFEL/PSI.

     Solution presented allows using intersections, phase shifters, and quadrupole movers already
     used at the European XFEL.

       Racks & cables: Most essential cables for first commissioning are in place.

       Vacuum system is complete and closed.

       Controls: Vacuum complete and in operation. Motion control under local testing and Karabo
       projects are being set up.

       Optics: Two offset mirrors and optics for soft-X-ray monochromator (2 pre-mirrors, 1 short
       grating, 1 long grating blank) are installed.

       First lasing is expected in the beginning of February. Commissioning of beam transport in
